Just hooked up my macbook to my new 37" Vizio LCD HDTV (720p). Used a mini-DVI to VGA adapter and a VGA cable, and a 3.5 mm mini jack cable for the audio. Worked like a charm. Plugged everything in, turned it on, and it automatically adjusted the resolution and looks awesome. So I'd suggest just using VGA rather than HDMI if your TV has the VGA input. It's a lot cheaper than buying a mini-DVI to DVI and a DVI to HDMI and an HDMI cable. Also, I used the mini jack cable for audio because my TV only has optical audio out, but I think it sounds pretty dang good.
